224 BRITISH ICHNEUMONS. [Ltssonoia. 



of August, 1897 and I took another on the flowers of Angelica sylvestris at 

 Harkstead in Suffolk on the ist September, 1903. Chapman bred a 

 female and two males from British Psyche vitermediella, along with a speci- 

 men of Hemiteks areaior which was probably hyperparasitic upon it {cf. 

 Ichn. Brit. ii. 133), on 22nd of June, 1899.

Alutaceously punctate, black and a little shining. Head broader than 

 thorax and narrowed behind the eyes ; cheeks subbuccate ; mouth and 

 clypeus stramineous, ^ also with cheeks, facial marks and the internal 

 orbits concolorous. Antennae filiform and slightly attenuate apically, a 

 little shorter than the body ; flagellum dull ferrugineous beneath. Thorax 

 narrower than the head, with fla^'ous in ^ or rufescent in 9 humeral 

 marks ; mesonotum immaculate and mesopleurae closely punctate above ; 

 metathorax finely scabriculous with the areola represented by a longitu- 

 dinal impression. Scutellum black. Abdomen oblong-subfusiform ; 

 basal segment curved, \'ery smooth, a little narrowed basally and aluta- 

 ceously punctate, not longer than the hind coxae, centrally subcanalicu- 

 late and transversely impressed before the apex ; second and' third hardly 

 broader than long and strongly alutaceo-punctate ; all the segments api- 

 cally red-margined ; the apical ones becoming gradually smoother to the 

 anus ; terebra straight or slightly reflexed, and about as long as the body. 

 Legs normal, red with the hind tarsi ferrugineous and the anterior coxae 

 and trochanters of the ^ pale. Wings slightly clouded ; stigma pale 

 infuscate, radix and tegulae pale stramineous ; areolet subsessile and 

 emitting the recurrent nervure beyond its centre ; nervellus intercepting 

 below the centre. Length, 5—6 mm. 



Holmgren gives a 9 variety with two testaceous facial marks and a 

 pale dot at the vertical orbits, and a J with the hind coxae partly piceous ; 

 he adds that this species may at once be distinguished from L.segmeniator, 

 with which it had formerly been co-mingled, by the puncturation and mark- 

 ings of the abdomen ; as well, says Thomson, as by the stronger abdominal 

 puncturation, more slender flagellum of which the basal joint is hardly 

 longer than the second. With L. iarinifrotis, Thorns., it agrees in its 

 immaculate mesonotum and superiorly very closely punctate mesopleurae, 

 but diff"ers from it in its more strongly punctate metathorax, etc. Sch- 

 miedeknecht considers that L. punctiventris is not synonymous with the 

 present species on account of some disparity in the length of the terebra 

 and central segments ; he may be correct, but Thomson expressly super-
